Learners conduct experiments with ice, water and steam to observe the water cycle. They discuss substances that water accumulates from the Earth as it moves through its cycle.

Do solids, liquids, and gases even matter? The presentation focuses on changes in matter, including phases, Boyle's Law, Charles' Law, and physical changes. 

Crazy fact—freezing liquid actually gives off heat! Young scholars investigate the transfer of energy when liquids freeze using a chemical heat pack. The heat pack gives off heat as its liquid core freezes.

The effects of rising sea levels on Isle de Jean Charles, located off the coast of Louisiana, are documented in Emmanuel Vaughan-Lee's poignant short video. Viewers are asked to consider not only the plight of residents but also what...

Students conduct a web-based project to analyze recent or on-going climate change research in the North. They are exposed to the application of science in current research on climate change.

For this chemistry worksheet, students calculate the freezing point of a given solution. Students calculate the final temperature and state of the water in a given problem. Students solve several problems provided.

Students are told that objects in contact with one another reach an equilibrium temperature. A hot object placed in a cool liquid always cool off. It never happens that the object gets hotter and cool liquid gets colder. Students predict...

Students investigate what happens to solids and liquids when they change from one form to another. The amount od space taken by frozen water begins the discussion and students are led to formulate their own hypothesis to research.

Ninth graders conduct an experiment to determine how melting sea ice affect sea level. In this earth science lesson, 9th graders explain the environmental consequences of rising sea level. They relate this lesson to global warming.

Young scholars investigate the kinetic-molecular theory. In this state of matter instructional activity, students consider the differences of melting glaciers, melting icebergs and investigate on what happens when submerged water melts.

Fourth graders study evaporation and condensation as parts of the water cycle. First they determine the similarities and differences between a cup of water and an ice cube before measuring the volume of ice before melting it, and...

Young scholars complete activities to study the properties of solids and liquids. In this states of matter instructional activity, students investigate the melting and freezing of a range of materials in a virtual experiment. Young...

Second graders investigate the effect of melting glaciers to sea level. In this earth science lesson, 2nd graders simulate the process in the lab by conducting an experiment using ice cubes and clay. They explain the consequences of...

First graders investigate how water can be both a liquid and a solid. They weigh popsicles and observe them as they write in their science journals. They measure the liquid as the popsicle melts and refreeze them to change them back...

Students explore the water cycle. In this water cycle instructional activity, students simulate the water cycle by placing an ice cube in a Ziploc bag and observing the changes which occur over time. Students record the mass of the...

Learners investigate water as an agent of change. They conduct an experiment involving a mound of soil, observe and record any changes that occur when ice melts on the mound of dirt, and create a drawing of the changes that take place...

Learners work in small groups. They grab a handful of ice, and place the ice in an empty beaker of ice using a triple beam balance. Students heat up the beaker of ice over a hot plat until the ice has changed into water. They measure...

Students examine icebergs and how they are suspended in water, why ice floats, the melting process of an iceberg, and the floating behavior of ice compared to that of a cork through a lab activity.

Students explore the states of water. In this physical science lesson, students use ice and dry ice to observe the changes in the state of matter. Students record the results.

First graders investigate the different water formations by conducting an experiment.  In this water properties lesson, 1st graders examine jars filled with ice, rain water, air and snow in their class.  Students predict what...

Students place themselves in the position of a water molecule, ice molecule, or steam molecule and then describe the process of changing phase.

In this solid to liquid worksheet, students use ice cubes and water to see how the volume of water changes when solid water turns to liquid. Students follow 4 directions and answer 5 questions.

Students experiment to show the three forms of water. They watch a "hand" made of ice as it melts observing and drawing what they see.

Third graders discuss four points related to conservation. They work in groups to design a package to keep an ice cube from melting to demonstrate the concept of insulation. They then make a chart that shows which materials used did the...
